What is Previa Family?
Previa keeps your health records, and your family's if they choose, in one place, in order over time. It explains reports in plain language with a source for every point, reads your wearables, and helps you prepare for appointments.
When does Previa launch?
We'll announce the date in November. Waitlist members get in first, a month before everyone else, and we'll email your invitation on launch day.
Can I use Previa just for myself?
Yes. Start on your own and add family whenever you like. Your tree grows a branch when someone joins.
Which phones?
iPhone and Android.
Which countries?
At launch: the United States, Canada, the United Kingdom, India, Singapore, Australia and New Zealand.
Who can see my health information?
Only the people you choose, category by category. Joining a family doesn't share anything by itself, and you can take access back at any time.
My family lives in different time zones. Does that matter?
No. Reminders arrive at each person's local time, and everyone sees updates as soon as they're shared.
What happens in an emergency?
Your emergency profile is one tap away, with your allergies, treatments and contacts. Previa doesn't contact emergency services for you; the call buttons dial from your phone.
Which wearables work with Previa?
Previa reads from Apple Health on iPhone and Health Connect on Android. Devices whose apps share into these work with Previa: for example Apple Watch, and rings, bands and watches from brands such as Oura, WHOOP, Garmin and Samsung, plus Fitbit through Google's apps. Previa doesn't connect to device apps directly.
What does Previa read from my devices?
Steps, sleep, resting heart rate, heart rate variability, VO2 max estimates and blood oxygen, when your device shares them. Each device shares different measures, so some may be missing. Previa shows only what arrives, as weekly device estimates.
Does Previa change anything in Apple Health or Health Connect?
No. Previa only reads, and only the measures you allow in your phone's settings. You can switch it off at any time.
Who is Kahu?
Kahu is a health companion for everyone on Previa. It helps you find your way around, explains your records with sources, shares what published guidelines say, and helps you prepare for doctor visits. Kahu is an AI. It doesn't diagnose or treat, and it doesn't replace your doctor.
Does Kahu keep my chats?
No. Each chat is deleted when you close it. Only what you choose to save, like a visit preparation, stays in Previa, and you can delete it.
Does Previa use AI on my records?
Yes, to read and explain the reports you confirm, always with sources. Kahu sees your information without your name or contact details. Your data is never used to train AI models.
Is this medical advice?
No. Previa explains and organises. Decisions about diagnosis and treatment are for you and your doctor.
Where is my data stored?
In the United States, with our hosting providers, encrypted at rest.
Can I delete everything?
Yes, straight away, in one step. You can download your records first.
Does Previa sell my data or show ads?
Never.
Who runs Previa?
Previa is built by Previa Family, Inc. (in formation), founded by Yash Jain, a doctor. Yash doesn't review anyone's results, and nobody at Previa does.
How much does it cost?
Waitlist members get the first month free, with every feature. A month later, plans for individuals and families begin, and everyone gets 2 weeks free first. We'll share the prices before then.
Do I need a card to start?
No. Joining the waitlist and your free time need no card, and nothing is charged unless you choose a plan.
